TO ALL WHOM I'I MAY CONCERN:

Be it known that I, HENRY YOUNT, of Dayton, in thc county of Montgomery,in thc State of Ohio,have invented a new and improved Mode ofConstructing Looms; and I do hereby declare that the following is a fulland exact description thereof', reference being had to the accompanyingdrawings, and to theletters of reference marked thereon.

The nature ot' my invention consists in providing lateral guides for thcharness-frames, and the manner of `giving motion to the same.

To enable others skillcd in the art to make and use my invention, I willproceed to describe its construction and operation.

The figure represents a side view of o. loom containing my improvements.

A represen-ts a quadrangular frame, the dotted lines at H and P showingthe position of the cross-pieces. 'lo the cross-pieces H H are attachedthe guides F F, which have a series 'of grooves in which theharness-frames B move. To each of the fra-mes is attached an arm, C, andto each arm C is pivoted an arm, D. The lower end of the arm C isprovided with a curved slot, p, and through this slot and into arm Dpasses a setsscrew to retain the two arms together. The arms D areconnected to the levers K K by a pin, and these levers have aser-ies ofholes by which thc movements of the harness-f`rames may be increased ordiminished, and the screw in the curved slotp holds the arms C D rigidlytogether after the pin on thc arm D is in thc desired hole in' theVlever KY To the cross-piece P are attached posts E, through which a pinpasses, forming a `fulernn for the levers K. On the opposite side ofthscrosspieee are attached the guides I, and likewise thesupporting-pieces O, which bear the shaft to which the cams areattached. An exact description of the cams is unnecessary, as they areidentical with those in common us'c, and give to the levers analternating movement, which are likewise similar to those lin use. Thecrank r is attached to the shaft to show the movement. In a practicalmachine the eamshaft is connected to the main shaft of the loom by abevel-gear.

I have shown but two cams, levers, and harness-frames, but I do notdesire to limit myself to any particular number of cams, 85C. i

Operation: On turning the cams the levers are made to oscillate, thuscommunicating to theharness-f'rames the requisite motion for weaving.

Having described my invention, what I desire to secure by LettersPatent, is-

The combinationfof the arms C and D, levers K, cams Gr, and frame A.constructed and arranged as -and for the purpose set forth` HENRY YOUNT.
